Julia Roberts and Emma Roberts
Emma Roberts grew up visiting her famous aunt on set, and the two both appeared in the 2010 rom-com Valentine’s Day. (Emma also payed homage to Julia a few years ago on Halloween, when shedressed up as Vivian from Pretty Woman.)
Snoop Dogg, Brandy, and Ray J
It’s no secret that Ray J and Brandy are siblings, but they also have a famous first cousin: Snoop Dogg. Snoop and Brandy have even collaborated on the rapper’s song “Special”.
